The game features 50 achievements totaling 1000 points. Most of the achievements are the same as the 360 counter-part, with the clever addition of the "Not So Serious" achievement that calls for 10,000 kills in Player matches, rather than Ranked matches. The "Seriously..." achievement for killing 10,000 in Ranked matches is still present, forcing players to now have 20,000 kills total, unless the achievements stack together if you get them in Ranked matches first.
There is also one secret achievement, which is most likely for killing the new boss character (the Brumak), presumably on Hardcore (or higher) difficulty like the other boss achievements.
